Technical Information on Sockets

When you're starting a do-it-yourself type project, it can be difficult to know all the tools, fasteners and mechanisms that are necessary to get the job done right. When it comes to fasteners, sockets may be your best bet, depending on the type of project you're doing. They are usually ideal for situations that require assembly within a very close tolerance, as they can be placed very close together without any side clearance issues.

While all types of sockets can be controlled with an allen wrench drive, there are still many other features that distinguish them from one another. Here is a guide to the technical intricacies of the different types of socket hardware.

Set Screws

Socket set screws have no head on them and machine threads can be used in the tapped hole. They are six-sided, usable with an allen wrench and come in two main varieties:

  • Stainless steel 18-8 : Set screws are composed of stainless steel 18-8, which is the most common form of steel for general hardware.
  • Alloy steel black oil finish :This type of set screw is manufactured from an extremely high strength heat from alloy steel. The color is a black oil, or plain, finish.

Head Cap Screws

Socket head cap screws have a hexagon in the center that can be controlled with either a standard allen wrench or a hex key. There are many different types, including:

  • Standard head
  • Button head
  • Flange head
  • Low head
  • Self locking
  • Vented head

The materials of a socket head cap screw can be any of the following:

  • Stainless steel
  • 18-8 stainless steel
  • 316 stainless steel
  • Steel
  • Alloy steel
  • Plain steel

Which type of set screw or head cap screw you use will depend entirely on the needs of the project. If you need further information about these products before determining exactly what type of fastener to use, don't hesitate to call a reputable hardware store that can help answer any questions you may have.
